Don't Scrap America's Alliances. Fix Them.

DOES THE United States benefit from having allies? In recent months, Donald Trump, the presumptive Republican presidential nominee, has voiced skepticism about the value of core American allies in Europe and East Asia. Trump argues that U.S. allies are free riding off the United States, and that their contributions to U.S. security are no longer sufficient to justify either the risks or the costs they impose on Americans. He is far from alone this election season. Surrogates for Bernie Sanders like Jeffrey Sachs have made similar arguments.
